Comparative Effectiveness of Cloth Sampling to Rinse Sampling on Microbial Recovery and Salmonella Detection in...

Area of Science:

• Food safety and microbiology
• Agricultural science
• Food processing technology

Background:

• Poultry is a major protein source but can transmit foodborne pathogens like Salmonella.
• Current United States Department of Agriculture (USDA) rinsate sampling methods render poultry products inedible, causing economic losses.
• There is a need for efficient, non-destructive sampling methods in the poultry industry.

Purpose of the Study:

• To evaluate the efficacy of a novel spun-polymer cloth sampling tool, MicroTally® Mitt, as an alternative to the USDA rinsate method.
• To compare Salmonella prevalence, aerobic bacterial counts, and coliform counts between the two sampling methods.
• To assess the impact of sampling method on poultry meat quality and waste.

Main Methods:

• Comparative analysis of MicroTally® Mitt and USDA rinsate method on chicken wings and skinless thighs.
• Quantification of Salmonella prevalence, aerobic bacterial counts, and coliform bacterial counts for both methods.
• Statistical analysis to determine consistency and significance of differences between methods.

Main Results:

• The MicroTally® Mitt demonstrated consistent results (P > 0.05) for Salmonella and coliform detection compared to the USDA rinsate method.
• Slight, but not biologically significant, differences in aerobic bacterial counts were observed (P < 0.05) between methods, varying by chicken part.
• The cloth sampling method minimizes material shedding and allows for efficient sample collection.

Conclusions:

• The MicroTally® Mitt is an effective and consistent alternative to the USDA rinsate method for poultry sampling.
• This novel tool reduces food waste and financial loss by preserving product edibility.
• The MicroTally® Mitt supports enhanced food safety protocols in the poultry industry without compromising accuracy.
